CryptoWall .wtdi – How Does It Infect
The primary method of infecting victims with this ransomware virus is via taking advantage of the inexperienced users by sending massive e-mail spam. The messages within the sent e-mails contain deceptive messages that aim to convince the victim to either click on a web link that causes a malicious redirect or open a malicious e-mail attachment. E-mails may have deceptive content, like the following:
The web link in the example above, then leads to a fake web page of DHL which automatically triggers a download of a .zip archive in which the payload of viruses, like the .wtdi CryptoWall may be contained in loaders. These loader type of files, when opened may extract the payload of the virus on the infected computer.
Other methods by which you could become a victim of the CryptoWall .wtdi ransomware virus are by downloading fake setups, clicking on malicious web links posted on suspicious sites, or downloading fake updates or installers of software.

During the infection process, the loader file downloaded from the spam e-mails or other distribution methods may drop the main payload file, named CryptoWall.exe as reported in VirusTotal:
Then, the ransomware may set the file to run automatically on Windows start-up. This is achievable by modifying the Windows Registry Editor, more specifically the following sub-keys:
- Run
- RunOnce
In those sub-keys, value strings with custom data are added. They may have random names, or the name of the executable, in this case CryptoWall. The malicious string has the location of the CryptoWall.exe file.
After this has completed, the .wtdi file virus may also delete the shadow volume copies on the infected computer. This is achievable by executing the vssadmin command in administrative Windows mode. This command is responsible for deleting those copies and eliminating all of the chances to retrieve the encrypted files via this method. The command is in different parameters, like the image below displays:
